STEINER-PARKER SYNTHACON MODEL 174 SN 1301 B

Note: Auction links are affiliate links for which the site may be compensated.

via this listing

"The Steiner-Parker Synthacon is a monophonic analog synthesizer that was built between 1975 and 1979 by Steiner-Parker, a Salt Lake City-based synthesizer manufacturer. It was introduced as a competitor to other analog synthesizers, like the Minimoog and ARP Odyssey. The Synthacon includes three voltage-controlled oscillators, a two-pole resonant Sallen Key filter, two ADSR envelope generators, a pink and white noise generator, and a 49-key keyboard. While the Synthacon was not a modular system, signal routing could be achieved through a series of switches."

7/22/23 DEMO: EML 200 (x2) + Ton Atelier Lauter eurorack EML 101 clones (for sale)

video upload by Cfpp0

"This is a demonstration of the (great) sound of two eurorack modules by Ton Atelier Lauter. They are clones of the EML 102 VCF and the VCA/ring modulator. Feeding them actual EML oscillators seemed appropriate for the demo and sounds good.

The note cards will tell you which mode the filter is in."

via this auction

"Ton Atelier Lauter is in Germany. I imported this VCF originally to use with my EML 200, which doesn’t have voltage control over the filters. Somehow the 200 got surrounded by DOT COM filters and Metasonix TM boxes and the Ton Atelier Lauter EML 101 VCF clones got sidelined (See my other listing for the EML 101 RingMod/VCA).

So it’s up for grabs. If you don’t know EML, but like that Steiner Parker Synthacon sound or that MS20 mk1 sound then you might like messing with this. Comes in original box with power cable."

EMEAPP SONIC TEST DRIVE: STEINER-PARKER SYNTHACON Feat. DON SLEPIAN

video upload by EMEAPP

"That filter! Need we say more. The fabled Steiner-Parker Synthacon is a three oscillator beast of a portable mono-synth capable of immensely fat tones, is highly regarded for its tuning stability and is chock full of awesome control and modulation options. However, the star of the show is the Synthacon's peerless multi-mode LP/BP/HP which has cultivated an identity of its own and has achieved legendary status. Its a fantastic bit of electronic engineering and it truly behaves in a unique manner as compared to its contemporaries. Join Don Slepian as he takes a dive into the Sytnthacon and puts the filter through its paces."

STEINER-PARKER SYNTHACON - Analog Synth Demo

video upload by synth4ever

"Steiner-Parker Synthacon vintage analog synthesizer demo. This demo of the rare Synthacon mono synth from Steiner-Parker features various sounds and tweaking. Filmed at the Vintage Synthesizer Museum in Los Angeles, CA.

The Steiner Parker Synthacon is a rare monophonic analog synthesizer produced in 1975-1979. It features 3 VCOs, white & pink noise generator, sample & hold, portamento, 2-pole resonant lowpass/bandpass/highpass filter, 2 ADSR envelopes, trigger generator, 49 keys, and a ton of signal routing via numerous switches.

Only a few hundred Synthacon synthesizers were produced, according to designer Nyle Steiner. It's capable of nice sounds of course, but it excels at chaotic and crazy modulations, squelches, ring mod tones, noises and has an extremely potent filter with resonance. The legacy of the Steiner-Parker Synthacon's filter design lives on today in some modular synth designs as well as some Arturia products.

It was a lot of fun to try the Synthacon and tweak it, as all the switches make it very interactive for quick signal routing. If you have the opportunity to try one, don't pass it up!"

Note a new SYNTHACON is in the works.

Steiner-Connolly Synthacon In the Works

Spotted this one over at Synthtopia.

Here's what Steiner-Connolly had to say about it:

“For those of you who haven’t seen it yet, the Synthacon is back!

This is an authentic, discrete, through hole recreation of this iconic 70’s synthesizer under the direction of Nyle Steiner himself.

We have added midi via a FATAR keybed, and a couple new features, but this unit has been tediously recreated right down to the original circuit board design and vintage components.”

The Steiner-Connolly Synthacon is available now to pre-order for $3,000 USD. Contact the company at support@steiner-connolly.com for details."

You can find tons of posts mentioning the Synthacon and various adaptations including individual modules and systems in previous posts here. One of my favorites though, is this demo by Todd Barton aka vgermuse. That sucker sounded brutal.

Vintage Original Steiner Parker Synthacon

"Steiner Parker Synthacon original, recently totally overhauled/serviced. I think this synth sounds more interesting than most vintage synths like the minimoog/2600/synthi, it has a real wild 70’s sound with raw oscillators and juicy filter, it’s unpredictable sounding in the best way possible. Local pickup in San Francisco, please contact me prior to purchasing to arrange payment and pickup."

Steiner - V.C. Hi-Lo Pass Resonant Filter & V.C. Trigger Generator - Prototypes 1975

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"FS: N.A. Steiner (Pre-Steiner Parker) - V.C. Hi-Lo Pass Resonant Filter and V.C. Trigger Generator - Prototypes

Here is another unusual listing from my collection. 2 very early synthesizer modules designed and hand built by Nyle Steiner in 1974 or 75 before the formation of Steiner Parker.. The Filter is perhaps THE ORIGINAL resonant multimode VCF designed by Steiner for his Synthasystem Modular System (also used in later used in other designs such as the Synthacon).

I have owned these pieces for almost 20 years, they are unmodified and have never have been repaired.. both still work and the filter sounds incredible.

This is a very rare chance to pick up a piece of vintage audio history, which you can also use musically!"

Switched On Austin - Synth studio & store tour | Austin, TX

https://www.switchedonaustin.com

A synth studio and store tour of Switched-On in Austin, Texas -- including the Switched On synthesizer showroom, walk-through of the Switched On synth store and brief highlight of the synthesizer repair area.

During a trip to Austin in early 2020 I had a chance to revisit the Switched On synth shop I first toured in 2018 [video bellow]. Switched On have since moved from their original location to a new spot and are under new ownership, so it was a great opportunity to see the new synth store.

This synth studio and store walkthrough showcases Switched On's extensive record collection, tape machines, various synthesizers, modular gear, classic vintage synths, rack units and more. To learn more about Switched On, visit https://www.switchedonaustin.com

Synthesizer von Gestern (Synths of the Past) Vol 2, Matthias Becker.

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Beautifully-produced second volume of Matthias Becker's authoritative 'Synthesizers of the Past' book - in German, but with so many superb illustrations that it's hardly necessary to read the text. New, unused, still sealed. The photos were taken of another copy of the book.

Too many highlights to mention all, but the book covers such absolute classic synths as the Trautonium, ARP 2500, EMS Synthi 100, E-mu Modular, Steiner-Parker Synthacon, RMI Harmonic Synthesizer, Birotron, PPG 1002, Moog Taurus and Liberation, Roland System 700, Synlab Modular, Roland SH-7, Crumar DS-2, Korg Sigma, ARP Quadra, Roland RS-505 and VP-330, Fairlight CMI, Realton Variophon, Oberhaim OB-Xa, Xpander and OB-SX, Gleeman Pentaphonic, RSF Kobol, Emulator 1, Synergy, Roland SH-101, TB-303, TR-606, MC-202, Jupiter 6, Syntec Banana, SCI Prophet T8, OSCar......... an incredible roster which would (in the beautiful condition they are in the photos) probably now be worth over half a million US dollars.

All with superb photos by Dieter Stork. Hardback, beautifully printed on very high quality paper, bound to the highest standards. A coffee-table book which is also a superb source of information. The Rolls-Royce (OK, Mercedes) of synth literature. (I should know - I produced the Ford Fiestas of the genre.) ISBN 3927954012, printed in 1995."

Update: I asked Lance if he knew how many clear Gleeman Pentaphonics were produced. Here's what he had to say: "Not sure how many Gleeman Pentaphonic Clear's there are. Rumored to be around 25. Funny enough, the guy I bought this one from lived in San Jose, which is just a few miles from where the Gleeman brothers were producing their synths. He told me that the one we have was originally a black one, but when they came out with the clear one, he had them retrofit it into a clear one, so he could wear it as a keytar and walk around with it on stage."
